Description
Sudhishna, Mondal, and Mondal squeeze gelatin rock models in 2026 to watch how injected fluid cracks layered stone, a scaled-down mirror of fracking in shale reservoirs. Their custom press applies load from two directions while cameras record fractures growing in real time through the transparent analogues. Water, thick SAE 140 oil, and oil-toluene mixes were injected at a steady 1 milliliter per minute under fixed confining and top loads.
Fracture shapes were measured frame by frame, tracking length and aspect ratio as the cracks chose paths through layered and uniform blocks under the loads applied. Computer simulations using a phase field damage model, which lets cracks emerge from the physics rather than being drawn in, reproduced the experiments well in the comparisons. Both also matched the classic analytical fracture model qualitatively, and the authors say the setup can serve carbon storage and gas hydrate studies as well.
